IRRIGATING-PIPE.

Specification of Letters Patent.

Patented Dec. 3, 1907.

Application filed January 21. 1907. Serial No. 353.249.

To all whom it may concern: 1

Be it known that 1, WILLIAM CoNNoLLY, a citizen of the United States, and a resident of Fort Benton, in the county of Chouteau and State of Montana, have invented a new and Improved Irrigating-Pipe, of which the following is a full, clear, and exact description.

The purpose of the invention is to so construct the end portion of the water supply pipe that is passed through the levee of an irrigating ditch or canal that the receiving end of said pipe may be closed or opened at will, and so that the amount of water passing through said pipe can be regulated to meet existing conditions. A further purpose of the invention is to provide means whereby the pipe will not be dislodged from its position by the pressure of the water in the supply basin that it enters.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth and pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a vertical section through a portion of an irrigating ditch or canal and a side elevation of the improved supply pipe in position in the levee; and Fig. 2 is a section through the receiving end of the pipe, the section being drawn upon an enlarged scale.

A represents a body of water adapted for irrigating purposes, being confined by levees B, or their equivalents, and 0 represents the inner section of the delivery pipe or conducting pipe, the inner end whereof extends through the inner face of the levee, and is in contact with the body of Water A. The inner end of said delivery pipe C is provided with an outwardly-extending annular flange 10 of any desired depth, and around the flanged portion of said pipeC a bed of material 1 1 is packed, which is of a harder character than that of which the levee is formed, and said material 11 can contain a certain amount of cement or other binder if so desired.

In connection with the receiving end of the pipe 0 a series of tubular stoppers D- is employed, said stoppers being nested and when all the stoppers D are in position in the receiving end of the pipe'C said end is completely closed.

The stoppers D are graduated in diameter. The innermost stopper, which is the smallest one, consists of a body section 12 open at its outer end, its inner end 13 being closed; and at the closed inner end ofthe central or smallest stopper D, an outwardly-extending flange 14 is formed, and a gasket or washer 15 secured upon the rear face of said flange, having close connection with the exterior of its body 12. 1

In the construction of the other stoppers, or those that surround the central one, said stoppers are open at their outer and also at their inner ends, and each of said outer stoppers consists of a body section 16 and a flange 17 at the forward or receiving end of the body, the flange 17 extending outwardly from said body and an outer concentric wall 16 extends from the body 16, a space 17 intervening the said wall and body as is shown in Fig. 2. The outwardly-extending portion of each flange 17 is provided with an attached washer or gasket 18, that engages closely with the outer wall 16 of the body 16, but the washer 15 for the central or smallest stopper engages directly with its body; therefore, when the stoppers are in position in the pipe C the gaskets or washers 18 make a complete water seal, and the outer flange of one stopper covers the inner flange of an adjoining stopper and the two walls of the outer stoppers serve to properly space one from the other.

All of the stoppers are provided with attached rings 19 or the equivalent thereof,

.so that any particular stopper may be removed at will so as to increase or decrease the diameter of the receiving end of the pipe C and consequently regulate the amount of water that shall pass from the basin into which the pipe extends.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent,

1 The combination with an irrigating pipe, having a marginal flange, of a closure therefor, comprising a plurality of stoppers, the central stopper being closed at its inner end, the other stoppers comprising inner and outer walls, the inner walls engaging with the next smaller stopper, and the outer with the next larger stopper, each of said stoppers being provided with an outwardly projecting the next larger stopper, each of said stoppers annular flange overlapping the flange of the next larger stopper, each of said flanges having a gasket secured to the outer face thereof.

2. The combination with an irrigating pipe, having a marginal flange, of a closure therefor, comprising a plurality of stoppers, the

central stopper being closed at its inner end, the other stoppers comprising inner and outer Walls, the inner walls engaging with the next smaller stopper, and the outer with being provided with an outwardly projecting annular flange overlapping the flange of the 15 next larger stopper.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WILLIAM CON NOLLY.
